Infinite loop in start menu #827

Open outpaddling opened 1 year ago

outpaddling commented 1 year ago

Aside from a few cosmetic issues, I've been experiencing one rather annoying issue on rare occasions. Upon clicking the Start menu, lumina-desktop gets stuck in an infinite loop. If I kill it, remove ~/.config/lumina*, and rebuild the config from scratch, everything is fine again for a while. Last time it happened, I used kill -ABRT lumina-desktop to generate a core file. The backtrace from lldb shows a cycle. Maybe this will provide some clues. If not, I can also reinstall Qt components with debug info to source code line #s.

lldb -c lumina-desktop.core lumina-desktop

This issue seems to have gone away on its own. I'm guessing it was a problem with one of the Lumina's dependencies.

outpaddling commented 1 month ago

The problem is back again. Below is a new backtrace from kill -ABRT.

This only seems to happen after resizing the start menu and logging out. After logging in again, the desktop freezes when opening the start menu.

Also, removing the folders from the favorites list seems to prevent the problem. ( Lumina automatically adds Documents and a couple others to the start menu favorites. )

Nothing has changed in the start menu source code, so i'm pretty sure its not something with Lumina. It might be a weird behavior coming from a change in qt. Have you updated recently? I only use the classic application menu, so I don't have any experience with the favorites thing in the other start menu options.

outpaddling commented 1 month ago

I ran updates yesterday, but I don't think there were any Qt5 updates. There were a few Xorg updates. Mainly wanted to post the workaround for the benefit of others. Any work happening on Qt6, BTW?
